C# Accessing a sharepoint site using the hostname and relative site path using Graph API

Question

My requirement is, with proper permissions in SharePoint, I should be able to get the Site details using the Graph API by specifying the SharePoint domain (host) name and site path.

• User [testuser@harsh.com .com] is already added as Owner to the Private Group [sites/MyPrivateGroup]
• I am able to log in to the SharePoint site from the browser using the testuser@harsh.com .com ID without any errors.
• Able to upload files, created document libraries, and edit files using the same id - When trying to access the site using the Graph API, getting the following error "error": {
          "code": "InternalServerError",
          "message": "Unable to find target address",
          "innerError": {
              "date": "2022-05-24T13:36:46",
              "request-id": "b7b083a7-5345-4380-9f68-416ace4e0a63",
              "client-request-id": "f5f6f16b-5011-7c0f-0b41-26e24daad709"
          }

I tried the following Graph API Endpoint via Microsoft Graph Explorer
https://graph.microsoft.com/v1.0/sites/{host-name}:/{server-relative-path}

{host-name} - "myofficedomain.sharepoint.com"
{server-relative-path} - "sites/MyPrivateGroup"

Any help would be really appreciated.

Thank you

Hi @S.Raghu Nathan ,

Hope you are doing well.

With C# code and graph SDK, you can try below code to get a sharepoint site using the hostname and relative site path.

GraphServiceClient graphClient = new GraphServiceClient( authProvider );

var site = await graphClient.Sites["{hostname}:"].Sites["{server-relative-path}"].Request().GetAsync();

Hope this helps.
